Sendlein sustained a torn medial collateral ligament in his left knee on the
team's opening possession of Sunday's 31-17 loss to the St. Louis Rams. He
played the remainder of the game despite the injury.

The 28-year-old Texas product has been a rock on the Cardinals' offensive line
since their remarkable run to the 2008 Super Bowl, playing in 80 consecutive
contests prior to Sunday's setback.

Rich Ohrnberger will be elevated to starting center in Sendlein's place and
the team also signed center Scott Wedige from the Cincinnati Bengals practice
squad.

Wedige re-joins the Cards after signing with team as an undrafted free agent
out of Northern Illinois. He spent the preseason with Arizona before being
released on Aug. 31.
